Catback Exhaust System
P/N – WS15-CBE
The TurboXS Catback Exhaust System features a TIG-welded, 304 stainless-steel construction. The pipe diameter spans 76.2mm with 1.5mm-thick walls, then reduces to 63.5mm after the Y-pipe split into the two mufflers. The pieces fit together with laser-cut 11.5mm flanges. This exhaust also includes a flex joint in the mid-pipe. At the rear-end, four large 101.6mm, slant-cut tips sport a burnt look for extra aesthetic points. The TurboXS exhaust sits on the heavier side, largely due to its bulkier mufflers, weighing in at 52.4 lbs. This also results in a very silent product, delivering a maximum decibel reading of only 89 during our test. Although quiet, this exhaust manages to increase power and torque output. Peak wheel horsepower jumped to 282.47whp at 5,800 RPM, nearly 5whp more than stock. Torque rose to 287.74 lb-ft at 3,700 RPM, 3.97 lb-ft more than stock. Most of the improvement in both horsepower and torque lay in the 3,500 RPM to 4,500 RPM range with increases of up to 12whp and 16 lb-ft.

Our Final Verdict
The TurboXS Catback Exhaust System comes off as a heavy-duty exhaust system, but at the expense of weight. However, we were impressed with the low sound levels it maintained, while providing some improvement in low-end power. This made for low cabin noise and additional torque to make city driving more convenient. Installation was simple without any problems in fitment.
